THR has a first look at Alfred Wertheimer's photos taken from 1956-59 included in a new book

But Rock Paper Photo, a curated online gallery of fine art photography, is releasing a collection of never-before-published images of the king taken by renowned photographer AlfredWertheimer from 1956-59.

Rock Paper Photo says it worked closely with Wertheimer to "unearth archives and curate these long-forgotten stills that show a very private side of Presley, extraordinary in their intimacy."

Some of these photographs were included in (or are outtakes from) a new book, Alfred Wertheimer: Elvis and the Birth of Rock and Roll. The 400-pager is being dubbed a collector's item: Only 1,706 numbered copies were produced, and they are all signed by Wertheimer.

The Hollywood Reporter has the first look at some of the images, which include listening sessions of his future hits "Don't Be Cruel" and "You Ain't Nothin' but a Hound Dog." Another shows him "slightly nervous" as he prepared for two performances of The Elvis Presley Show in Richmond, Virginia.

The parties also are offering prints in a variety of sizes and materials, including silver gelatin and archival pigment. Prices range from $500 to $3,500. Click here for more information.
